0 likes•152 views
This document discusses using a single channel EEG device to recognize emotions from EEG data. It collected data from 10 individuals labeled as stressed or relaxed. It preprocessed the raw EEG data using filters to isolate brain signals. It then used deep learning models including an LSTM network with and without attention to classify emotions. The LSTM with attention achieved 85% accuracy, which was an improvement over the LSTM without attention. Potential applications discussed include using EEG for stress reduction by customizing music, and emotion or word prediction. The document also discusses opportunities for future enhancements such as using convolutional layers or multi-modal networks incorporating additional physiological sensors.

Deep Learning for Recommender Systems with Nick pentreath
In the last few years, deep learning has achieved significant success in a wide range of domains, including computer vision, artificial intelligence, speech, NLP, and reinforcement learning. However, deep learning in recommender systems has, until recently, received relatively little attention. This talks explores recent advances in this area in both research and practice. I will explain how deep learning can be applied to recommendation settings, architectures for handling contextual data, side information, and time-based models, and compare deep learning approaches to other cutting-edge contextual recommendation models, and finally explore scalability issues and model serving challenges.

Future of systems analysis
Systems analysis involves analyzing systems to identify problems and design solutions to meet user needs more efficiently. It follows a process from research to evaluation. Systems analysts help businesses and companies by finding issues and developing innovative fixes. The author predicts that systems analysis will be in higher demand as technology advances rapidly and systems must continuously improve. Solutions may even replace human labor. Systems analysis will also exist if technology stops advancing but technology cannot progress without systems analysis. Apple is provided as an example that continually refines its systems to stay competitive. In conclusion, systems analysis will always be necessary to enhance existing systems for user convenience and efficiency.

Kasia discussed complexities of interpreting black-box algorithms and how these may affect some industries. She presented the most popular methods of interpreting Machine Learning classifiers, for example, feature importance or partial dependence plots and Bayesian networks. Finally, she introduced Local Interpretable Model-Agnostic Explanations (LIME) framework for explaining predictions of black-box learners – including text- and image-based models - using breast cancer data as a specific case scenario.
Kasia Kulma is a Data Scientist at Aviva with a soft spot for R. She obtained a PhD (Uppsala University, Sweden) in evolutionary biology in 2013 and has been working on all things data ever since. For example, she has built recommender systems, customer segmentations, predictive models and now she is leading an NLP project at the UK’s leading insurer. In spare time she tries to relax by hiking & camping, but if that doesn’t work ;) she co-organizes R-Ladies meetups and writes a data science blog R-tastic (https://kkulma.github.io/).

META-LEARNING.pptx
Meta-learning, also known as learning to learn, is a subset of machine learning that aims to improve the performance of learning algorithms. It does this by using the outputs and metadata from machine learning algorithms as input to optimize aspects of the learning process. This allows meta-learning algorithms to learn which machine learning algorithms work best for certain datasets and prediction tasks. They can then help reduce the number of experiments needed to find high performing models and build models that generalize well from only a few examples.
Exception handling in Pipelining in COA
An exception is an unexpected event that occurs within the processor, while an interrupt is an unexpected event from outside the processor. When an exception or interrupt occurs, the hardware executes interrupt handler code in the operating system kernel to handle the event. This may involve killing processes, outputting errors, or communicating with devices. The handler saves the context of the interrupted process, determines the cause, handles the event, then restores the context and resumes execution of either the original or another process.
Analysis & Detection of autism spectrum disorder using ML (3)_RKS.pptx

Improving Neural Abstractive Text Summarization with Prior Knowledge
Abstractive text summarization is a complex task whose goal is to generate a concise version of a text without necessarily reusing the sentences from the original source, but still preserving the meaning and the key contents. In this position paper we address this issue by modeling the problem as a sequence to sequence learning and exploiting Recurrent Neural Networks (RNN). Moreover, we discuss the idea of combining RNNs and probabilistic models in a unified way in order to incorporate prior knowledge, such as linguistic features. We believe that this approach can obtain better performance than the state-of-the-art models for generating well-formed summaries.

Multidimensional schema
The document discusses different types of multidimensional schemas used in data warehousing, including star schemas, snowflake schemas, and fact constellation schemas. A star schema has a central fact table linked to dimension tables, while a snowflake schema normalizes dimensions into multiple tables. A fact constellation schema combines multiple fact tables sharing dimension tables. The schemas vary in their structure, data integrity, flexibility, and complexity. Choosing a schema depends on the analytical needs, data relationships, and tradeoffs between simplicity and normalization.
Introduction to Pandas and Time Series Analysis [PyCon DE]
Most data is allocated to a period or to some point in time. We can gain a lot of insight by analyzing what happened when. The better the quality and accuracy of our data, the better our predictions can become.
Unfortunately the data we have to deal with is often aggregated for example on a monthly basis, but not all months are the same, they may have 28 days, 31 days, have four or five weekends,…. It’s made fit to our calendar that was made fit to deal with the earth surrounding the sun, not to please Data Scientists.
Dealing with periodical data can be a challenge. This talk will show to how you can deal with it with Pandas.
Chapter 6 pc
This document discusses message passing programming using three sentences:
Message passing programming partitions memory across processes and requires explicit parallelization through sending and receiving messages between processes. It outlines key concepts like blocking and non-blocking sends and receives, issues like deadlocks, and the use of buffers to allow asynchronous progress while maintaining determinism. Collective communication operations allow multiple processes to participate in coordinated message passing patterns.

Chain-of-thought Prompting.pptx
Chain-of-thought prompting involves dividing complex reasoning tasks into natural language steps to help large language models perform better. It has been shown to improve arithmetic word problem solving by prompting models to show the steps and equations used to arrive at the answer. An ablation study found that showing the intermediate steps led to better performance than just showing the equation or computed answer alone. While promising for improving reasoning abilities, chain-of-thought prompting may not truly elicit human-like reasoning and can be costly to apply due to annotation efforts and model sizes required.

Multi tasking learning
This document provides an overview of various multi-task learning (MTL) model architectures. MTL aims to improve generalization by learning multiple related tasks simultaneously using a shared representation. Key MTL architectures include hard parameter sharing, soft parameter sharing, shared trunk models with task-specific heads, multi-gate mixtures of experts, cross-talk networks, prediction distillation, BERT-based models for natural language tasks, multi-modal models, and learned architectures that determine the degree of sharing between tasks. Design challenges include negative transfer between tasks and combining multiple loss functions.
Traffic Prediction from Street Network images.pptx
While considering the spatial and temporal features of traffic, capturing the impacts of various external factors on travel is an essential step towards achieving accurate traffic forecasting. However, existing studies seldom consider external factors or neglect the effect of the complex correlations among external factors on traffic. Intuitively, knowledge graphs can naturally describe these correlations. Since knowledge graphs and traffic networks are essentially heterogeneous networks, it is challenging to integrate the information in both networks. On this background, this study presents a knowledge representation-driven traffic forecasting method based on spatial-temporal graph convolutional networks.
Llama-index
The document describes LlamaIndex, a toolkit that provides indices over unstructured and structured data to augment language models with private data through in-context learning. It discusses how LlamaIndex solves data ingestion and indexing problems to perform language model data augmentation in an efficient manner. Examples of how LlamaIndex can be used with different data connectors like Gmail, audio files, and Notion pages are also provided.
Report
This project aimed to create an iOS game where the player navigates a maze using brain signals from an EEG device and neural network classification of the signals. The project consisted of three programs: NeuroSample for collecting training data, NeuroTrain for training an neural network classifier on the data, and NeuroMaze the game itself. Key challenges included inconsistent EEG readings from the device, difficulty maintaining brain states for data collection, noisy data from facial muscle artifacts, and a small training dataset, leading to low classification accuracy not suitable for game play. The author learned that data quality is crucial for neural network success, and gained practical understanding of network parameters and training from this project.
The second seminar
This document discusses developing a generic EEG classification system using brain signals for brain-computer interface applications. The system architecture includes EEG signal acquisition, preprocessing to remove noise and artifacts, feature extraction using independent component analysis and power spectral density, dimensionality reduction, classification using convolutional neural networks, and postprocessing. The goals are to extract spatial and temporal information from EEG signals to classify different brain states and movements like hand movement, tongue movement, walking, eye blinks, and more. This will help build a robust EEG classification system to be used in various BCI applications.

EEG Signal Classification using Deep Neural Network
This document discusses using deep neural networks to classify EEG signals. It proposes using a convolutional neural network to analyze recurrence plots generated from EEG data in order to distinguish between focal and non-focal EEG signals. The recurrence plots are generated from EEG data collected from epilepsy patients. The convolutional neural network is then used to classify the recurrence plots to identify patterns associated with focal versus non-focal EEG signals. This classification of EEG signals could help doctors locate epileptic foci to inform treatment decisions.

Artificial Neural Network ANN
Artificial neural networks (ANNs, also shortened to neural networks (NNs) or neural nets) are a branch of machine learning models that are built using principles of neuronal organization discovered by connectionism in the biological neural networks constituting animal brains.
An ANN is based on a collection of connected units or nodes called artificial neurons, which loosely model the neurons in a biological brain. Each connection, like the synapses in a biological brain, can transmit a signal to other neurons. An artificial neuron receives signals then processes them and can signal neurons connected to it. The "signal" at a connection is a real number, and the output of each neuron is computed by some non-linear function of the sum of its inputs. The connections are called edges. Neurons and edges typically have a weight that adjusts as learning proceeds. The weight increases or decreases the strength of the signal at a connection. Neurons may have a threshold such that a signal is sent only if the aggregate signal crosses that threshold.
Typically, neurons are aggregated into layers. Different layers may perform different transformations on their inputs. Signals travel from the first layer (the input layer), to the last layer (the output layer), possibly after traversing the layers multiple times.
Spectral analysis and filtering
1) Filtering EEG data is necessary to remove artifacts but can distort the data if not done properly. High pass filtering is particularly problematic and may distort the data.
2) Power spectral density (PSD) analysis using the Welch method and Fourier transforms provides information about frequency components in EEG data but has limitations since brain signals are non-sinusoidal.
3) Parameters like window length and overlap affect PSD results, and defaults across analysis packages can produce different filtered outputs from the same data. Proper reporting of analysis settings is important.
Inroduction to BCI
1) A brain-computer interface (BCI) enables communication without muscular activity by detecting brain signals.
2) BCI applications include communication assistance, controlling devices like wheelchairs or robotic arms, and entertainment like games.
3) BCI systems work by acquiring brain signals, preprocessing them, extracting features, classifying intentions, and translating them into device commands.

The document proposes a method for using brain signals from EEG readings during deep breathing for biometric authentication. It discusses collecting EEG data during inhalation, holding breath, and exhalation and using feature extraction and classification algorithms like SVM and neural networks to classify the signals. The results showed deep breathing can produce stable alpha and beta brainwaves that can predict authentication with high accuracy regardless of the person's mental state. This approach could help address issues with other biometric authentication methods and improve permanence of the brain pattern over different states.
Neural networks
Neural networks are a type of data mining technique inspired by biological neural systems. They are composed of interconnected nodes similar to neurons in the brain. Neural networks can learn patterns from complex data through supervised or unsupervised learning methods. They are widely used for applications like fraud detection, risk assessment, image recognition, and stock market prediction due to their ability to learn from examples without being explicitly programmed.

Flood & Other Disaster forecasting using Predictive Modelling and Artificial ...Analytics India Magazine
Over 2.3 Billion people are affected due to floods in last 20 years and causing countless death , More than 92,million cattle are lost every year, seven million hectares of land is affected, and damage is over trillions dollars when taken globally in last 5 years. Floods are complicated natural events. It depends on several parameters, so it is very difficult to model analytically. The floods in a catchment depends on the characteristics of the catchment, rainfall and antecedent conditions. So the estimation of the flood peak is a very complex problem. Its due to the lack of Flood Prediction System which can predict the situation accurately. To Overcome this challenge we are building a Flood Prediction System using Predictive modelling. However we have divided our idea into small fragments but enough to be used globally. We have considered most flooded state of India, but can be used widely for all the low lying geographical regions. •The plains of Bihar, adjoining Nepal, are drained by a number of rivers that have their catchments in the steep and geologically nascent Himalayas. Kosi, Gandak,Burhi Gandak, Bagmati, Kamla Balan, Mahananda and Adhwara Group of rivers originates in Nepal, carry high discharge and very high sediment load and drops it down in the plains of Bihar. · About 65% of catchments area of these rivers falls in Nepal/Tibet and only 35% of catchments area lies in Bihar. · Bihar is India’s most flood-prone State, with 76 percent of the population, in the north Bihar living under the recurring threat of flood devastation. About 68800 sq Km out of total geographical area of 94163 sq Km comprising 73.06 percent is flood affected. · According to some historical data, 16.5% of the total flood affected area in India is located in Bihar while 22.1% of the flood affected population in India lives in Bihar. · From 1979 to Present day more than 8,873 Humans & 27,573 animals have lost their life due to flood. Some of Tools & Technology which is being used & can be used for Flood Prediction: •IBM. Watson Studio democratizes machine learning and deep learning to accelerate infusion of AI in to drive innovation. •An Intelligent Hydro-informatics Integration Platform for Regional Flood Inundation Warning Systems. •Three-Parameter Muskingum Model Coupled with an Improved Bat Algorithm. · Deep Learning with a Long Short-Term Memory Networks Approach for Rainfall-Runoff Simulation

AI is here, call it buzz, cause it a bubble, we are smack in the middle of an AI revolution. While there is a strong view building about consumer AI applications, there still seems to be some scepticism about AI for enterprises, primarily due to the lack of clarity and focus on how AI can actually deliver value for enterprises. At BRIDGEi2i, we believe it is important to have a non-fragmented view of the AI ecosystem and a “Value Roadmap” for AI in the enterprise context. As CxOs, it is important to understand where the enterprise is in the transformation journey and define value accordingly. This talk will throw light on how to look at the enterprise AI ecosystem and build the right roadmap for value.

Suppose that a customer who has given a high rating about a mobile phone writes the following review about the product: The front camera of the phone is excellent! Truly speaking, this is the best front camera I have experienced so far. From this review, we can understand two things. First, the customer holds a positive opinion about the phone. Secondly, the front camera of the phone is the targeted feature on which the opinions have been expressed in the review. In this workshop, we will be particularly interested in discovering patterns as indicated in the second case. We will discuss a framework that enables us to first discover the targets on which the opinions have been expressed in a review and then determine the polarity of the opinions. This kind of detailed analysis helps us to discover the components or features of the products which the customers have liked or disliked and thus help us to better summarize the information.

"Route risks using driving data on road segments" By Jayanta Kumar Pal Staff ...Analytics India Magazine
Going out for dinner in Mumbai during an extended stay, or planning for a long road-trip across the wild west of Rajasthan, the first thing one looks at is Maps, that informs the relative distance, estimated time and congestion areas of different routes for the drive. Zendrive built state-of-the-art technologies on its huge cache of driving data from smartphones and OBD, to add a significant dimension to the route mapping of Google, that is safety risk of the route. Essentially the technology is built on millions of drivers zipping through the route or segments thereof. Automobile Insurance expands in UBI- where it has been established that tracking a driver’s behavior behind the wheels (like Hard Brake, Speeding etc) can predict significant differences between their chances of collisions. Looking at the same event data from the road perspective, aggregating the relative event density on road stretches also predict the relative chances of collision on that segment. We have used map matching using GIS techniques, parametric density estimation and rare event modeling using quasi-Poisson GLM to analyze our data, build the models and finally implement the scoring system across the GIS route maps. Key learnings : Relation between dangerous driving events and collisions Route risk as an aggregate of all the drivers (or sample thereof) and their driving risk. The route you take for commute may determine your auto insurance. Outline : Usage Based Insurance : relation between collision rates and dangerous driving. Driving events : aggressive acceleration, hard brake, speeding, phone use, aggressive turns Poisson GLM modeling to predict collision rates using driving data Events on a road segment : map-matching using GIS techniques to split trips along road stretches, and aggregate such events along the spatio-temporal dimension across all drivers. Route risk of the road segment and any route comprising such segments. Driving risk along such routes and corresponding collision risks using transfer of the GLM model. Assignment of risks to drivers on their daily route of commute, to be used in UBI.

End-to-end pipeline agility - Berlin Buzzwords 2024
We describe how we achieve high change agility in data engineering by eliminating the fear of breaking downstream data pipelines through end-to-end pipeline testing, and by using schema metaprogramming to safely eliminate boilerplate involved in changes that affect whole pipelines.
A quick poll on agility in changing pipelines from end to end indicated a huge span in capabilities. For the question "How long time does it take for all downstream pipelines to be adapted to an upstream change," the median response was 6 months, but some respondents could do it in less than a day. When quantitative data engineering differences between the best and worst are measured, the span is often 100x-1000x, sometimes even more.
A long time ago, we suffered at Spotify from fear of changing pipelines due to not knowing what the impact might be downstream. We made plans for a technical solution to test pipelines end-to-end to mitigate that fear, but the effort failed for cultural reasons. We eventually solved this challenge, but in a different context. In this presentation we will describe how we test full pipelines effectively by manipulating workflow orchestration, which enables us to make changes in pipelines without fear of breaking downstream.
Making schema changes that affect many jobs also involves a lot of toil and boilerplate. Using schema-on-read mitigates some of it, but has drawbacks since it makes it more difficult to detect errors early. We will describe how we have rejected this tradeoff by applying schema metaprogramming, eliminating boilerplate but keeping the protection of static typing, thereby further improving agility to quickly modify data pipelines without fear.

ViewShift: Hassle-free Dynamic Policy Enforcement for Every Data Lake
Dynamic policy enforcement is becoming an increasingly important topic in today’s world where data privacy and compliance is a top priority for companies, individuals, and regulators alike. In these slides, we discuss how LinkedIn implements a powerful dynamic policy enforcement engine, called ViewShift, and integrates it within its data lake. We show the query engine architecture and how catalog implementations can automatically route table resolutions to compliance-enforcing SQL views. Such views have a set of very interesting properties: (1) They are auto-generated from declarative data annotations. (2) They respect user-level consent and preferences (3) They are context-aware, encoding a different set of transformations for different use cases (4) They are portable; while the SQL logic is only implemented in one SQL dialect, it is accessible in all engines.

Open Source Contributions to Postgres: The Basics POSETTE 2024
Postgres is the most advanced open-source database in the world and it's supported by a community, not a single company. So how does this work? How does code actually get into Postgres? I recently had a patch submitted and committed and I want to share what I learned in that process. I’ll give you an overview of Postgres versions and how the underlying project codebase functions. I’ll also show you the process for submitting a patch and getting that tested and committed.

None of the organizations that these individuals work for are responsible for the accuracy and completeness of the content or results. This work and presentations are for information purposes only.
- 7. DATA COLLECTION Collected Data: ▪ Single channel (FP1) EEG device ▪ Collected data from 10 individuals, multiple episodes ▪ Binary labels – ( Stressed, Relaxed ) ▪ Only Raw signal is used for this experiment Public Data: ▪ SEED ▪ DREAMER ▪ https://www.kaggle.com/phhasian0710/eeg-fpz-cz Public data is used to pretrain the network and experimented in embedding the signals.
- 8. PRE-PROCESSING RAW EEG ▪ Raw EEG consists of signals from different sources ▪ Muscle movements ▪ Eye movements ▪ Blinks ▪ Apply FFT / Butterworth band pass filters to separate out brain signals. ▪ EEG Lab ▪ MNE Tools ▪ Scipy ▪ Baseline the signal ▪ EEG Patterns vary with Age and hence it needs to be considered as a feature.
- 9. DEEP LEARNING FOR EEG ▪ Pretrain the network with a public dataset ( we used one from Kaggle ) ▪ Data from FP1 and FP2 ( public data) are averaged to form FPZ ▪ Select pre frontal points and average it, if the data contains multi channel ▪ Classifier trained to identify emotions like “dominance”, “high arousal”, “like” etc. ▪ Data collected from Neurosky is at 512 HZ ▪ Each reading is of size 7500 ▪ Raw signals, without FFT is provided as an input ▪ Limited architecture to compensate low volume
- 10. RESULTS ▪ Model Learnt to ignore eye blinks and other noises ▪ However pure LSTM model failed to focus on the right patterns ▪ Adding attention layer improved accuracy drastically. Metrics LSTM without attention LSTM with attention Accuracy 55 % 85 % F1 score 55 % 85 % Recall 55 % 85 % Precision 55 % 85.42 % Average accuracy Relaxed Stressed LSTM without Attention 43.75 62.5 LSTM with Attention 89.47 80.952
- 11. FUTURE ENHANCEMENTS ▪ Convolution layers to autofocus and reduce computational cost ▪ Signal Embedding is not considered however we believe it will improve performance ▪ More data collection with more subjects and standardized stimuli ▪ Multi Modal networks with inputs from ECG, GSR and EEG ▪ Time synchronized data consolidation from public sources.
